Based on v3.4-rc6 plus recently submitted device tree late_initcall patch: http://www.spinics.net/lists/arm-kernel/msg171620.html v3 changes: * removed file introduced in v1 no longer needed after v2 [per Shawn Guo] * re-ordered added #includes in alphabetical order [per Shawn Guo] * Remove if(!drv) check to allow handling by stack trace [per Sascha Hauer] * Added missing return value in error meesage [per Shawn Guo] * fixed (void *) casting problem pointed out Sasha Hauer. Used a different type of casting to properly give warning on improper casting: arm_pm_idle = (void (*)(void))imx5_idle; Used this casting instead of adding a dummy caller function because adding the dummy function appears to unnecessarily introduce the following additional operations: static void imx5_pm_idle(void) { a0: e1a0c00d mov ip, sp a4: e92dd800 push {fp, ip, lr, pc} a8: e24cb004 sub fp, ip, #4 imx5_idle(); ac: ebffffd3 bl 0 } b0: e89da800 ldm sp, {fp, sp, pc} v2 changes: * Removed some unnecessary spaces [per Jess Juhl] * Added return value for an error message [per Sascha Hauer] * Reworked init scheme to use device tree late_initcall [per Sascha and Shawn] * Moved imx6q and imx5 cpuidle functionality to existing files. https://lkml.org/lkml/2012/5/1/363 v1 initial submission: https://lkml.org/lkml/2012/4/16/644 Robert Lee (3): ARM: imx: Add common imx cpuidle init functionality.
